ROS Diamondback Beta 2 Release

Our second beta release of ROS Diamondback is now available (installation instructions). Thank you to the many users who have reported issues with the first beta release. We also appreciate the users who have updated Diamondback instructions for the many various platforms ROS is available on. A special thank you goes to Nicholas Butko, who provided numerous patches to improve OS X compatibility.

In addition to OS X updates, this release continues our rollout of Eigen 2/3 compatibility and also cleans up various stack dependencies and installation variants. There are still several fixes and updates we wish to deploy before we reach release candidate status.
